Feeding for success in
cage-free egg production
Supporting performance and welfare throughout lay is key
to making a profit.

arket pressures, growth in the cage-free
market and bird management issues
continue to challenge the egg sector. As
feed price volatility continues and margins are eroded,
producers and nutritionists need to find strategies to
improve the efficiency of egg production.
One technique is to increase the number of weeks for
which a flock is kept - more eggs for the same initial
outlay; however, the main challenge with hens late in lay
is maintaining persistency while controlling egg size and
achieving egg quality requirements. With beak-tipping
bans on the horizon for some, strategies to improve
welfare and prevent injurious pecking are a priority.

Longer laying cycles
Maintaining lay persistency, egg mass and shell
quality in late lay can have a significant impact on
flock financial performance. Hens lay fewer, larger
eggs and eggshell strength is reduced along with the
quality of albumen. Egg size should be controlled and
calcium intake optimized. Poor eggshell quality is a
major cause of downgraded eggs (seconds), a function
of reduced shell thickness and strength - due to less
effective calcium metabolism.
As well as overcoming these issues, late lay
management must ensure skeletal integrity is maintained and that birds remain on target body weight,
well feathered and in good condition. While
certain issues can be addressed once hens reach
approximately 60 weeks, others need to be considered from pullet onward.
